Abstract

An air induction system for filtering a compressible fluid to an electromechanical component mounted on a wheel of a vehicle. The system may make use of a first plurality of float valves arranged in series in a non-linear first flowpath path, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and one being in communication with an inlet of the electromechanical component. Each of the float valves may have a buoyant float valve element therein which is responsive to change position when submerged in water, to close off its respective float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.

First claim

What is claimed is:

1. A system for controlling admission of a compressible fluid to an electromechanical component mounted on a wheel of a vehicle, the system comprising:
a first plurality of float valves arranged in series in a first flowpath, with at least one of the float valves forming an inlet for intaking the compressible fluid into the first flowpath, and another one of the float valves being in communication with an inlet of the electromechanical component; and
each of the float valves having a buoyant float valve element therein responsive to change position when submerged in water to close a flow pathway through the float valve depending on an angular orientation of the wheel, and thus an angular orientation of the float valve.

2. The system of claim 1 , wherein the first flowpath including the first plurality of float valves includes four float valves arranged in series in a non-linear path, with one of the four float valves forming a first inlet able to receive the compressible fluid, while another one of the four float valves is in communication with the inlet of the electromechanical component.

3. The system of claim 1 , wherein adjacent ones of the first plurality of float valves are rotated so as to be non-parallel from one another in angular orientation.

4. The system of claim 2 , further comprising a second flow path including a second plurality of float valves, with one of the second plurality of float valves forming a second inlet for intaking the compressible fluid, and another one of the second plurality of float valves being in communication with the inlet of the electromechanical component.

5. The system of claim 4 , wherein two of the float valves of the first plurality of float valves are configured to receive the compressible fluid.

6. The system of claim 5 , wherein two of the float valves of the second plurality of float valves are configured to receive the compressible fluid.

7. The system of claim 6 , wherein the first and second flow paths are angularly spaced apart from one another, and each float valve in each of the first and second flow paths are angularly offset from one another to form a non-straight path.

8. The system of claim 6 , wherein the first and second flow paths collectively include a total of four float valves that are configured to receive the compressible fluid and are each rotated, with respective to an adjacent float valve, by more than 45 degrees around the circumference of the wheel.

9. The system of claim 1 , further comprising a filter disposed between the first plurality of float valves and the inlet of the electromechanical component for filtering the compressible medium before the compressible medium enters the inlet of the electromechanical component.

10. A system comprising:
a wheel;
an air compressor mounted on the wheel, the air compressor having an inlet; and
an air induction system mounted on the wheel for controlling an admission of air from an ambient environment into the inlet of the air compressor;
the air induction system including a plurality of float valves fixedly supported on the wheel and arranged in a non-linear flow path such that the admission of air into the wheel rim is blocked when the wheel is submerged in a fluid.

11. The system of claim 10 , wherein the air induction system includes a filter for filtering air from the ambient environment prior to the air being admitted into the inlet of the air compressor.

12. The system of claim 11 , wherein the float valves are arranged on the wheel to be angularly offset from one another.

13. The system of claim 11 , wherein the plurality of float valves and the non-linear flow path includes additional pluralities of float valves forming an additional non-linear flow path, the additional non-linear flow path operating to supply air from the ambient environment to the compressor inlet, and one of the other of the non-linear flow path or the additional non-linear flow path operating to block the flow of air and fluid into the compressor inlet depending on an angular orientation of the wheel.

14. The system of claim 11 , the non-linear flow path and the additional non-linear flow path are arranged so as to include portions separated from one another by 90 degrees around a circumference of the wheel.
